Objective To explore the related factors of early hematoma enlargement in patients with spontaneous intracerebral hemorrhage.Methods The clinical data of 142 patients with spontaneous intracerebral hemorrhage were analyzed.The first CT was performed within 6 h of onset and the second within 24 h of onset.Single factor analysis and multiple Logistic regression analysis were performed to determine the related factors of early hematoma enlargement.Results The incidence of early hematoma enlargement was 24.6％ (35/142).Multiple Logistic regression analysis revealed that the following four factors were independently associated with early hematoma enlargement:age (OR =1.069,P =0.003),systolic pressure (OR =1.865,P =0.026),sharp of hematoma (OR =2.712,P =0.028),using mannitol (OR =2.939,P =0.020).Location of hemorrhage and volume of hemorrhage were not associated with early hematoma enlargement (P ＞ 0.05).Conclusions Age,systolic pressure,sharp of hematoma and using mannitol are the important predictors of early hematoma enlargement with spontaneous intracerebral hemorrhage.In patients with older age,higher systolic pressure,irregularly shaped hematoma,close observation of hematoma enlargement should be made CT-scanning check.And the caution in the early use of dehydrating agent should be careful.

Objective:To observe the effects of sera Th1/Th2-typed cytokines in patients allergic rhinitis (AR) who were treated with kebimin decoction(KD),and to study the therapeutic mechanism of KD in AR.Methods:60 patients of AR were randomly divided into two groups (treating group,TG and control group,CG). Patients in TG were treated with KD,while those in CG were treated with Xinfang Rhinitis Capsule before and after treatment,the levels of serum Th1-typed cytokines IFN-?、IL-2、IL-12 and Th2-typed cytokines IL-4、IL-5、IL-10 were determined by enzyme-linked immune sorbent assay (ELISA); and compared with 30 healthy controls.Results:The levels of serum Th2-typed cytokines IL-4、IL-5、IL-10 were higher and the levels of Th1-typed cytokines IFN-?、IL-2、IL-12 were lower in AR than that in healthy control ( P 05).Conclusion:Kebimin decoction is highly effective in treating allergic rhinitis by regulating the levels of Th1、Th2-typed cytokines,correcting the imbalance Th1/Th2-typed cytokines network.

Objective To investigate the effects of probucol and losartan on cell proliferation after balloon angioplasty in hypercholesterolaemic rabbits.Methods Forty male New Zealand rabbits were randomly divided into high cholesterol diet group,probucol group,losartan group and combined drugs group.The iliac arteries of the rabbits were balloon-injured and the insulin-like growth factor-I receptor(IGF-IR),vascular endothelial growth factor(VEGF),and proliferating cell nuclear antigen(PCNA) were detected by using immunohistochemical method.Results Compared with high cholesterol diet group,the lumen areas were enlarged and the intimal areas were decreased in the probucol group,losartan group and combined drugs group(all P

AIM: To explore the effect of atorvastatin on cardiac remodeling in spontaneous hypertension rats(SHR).METHODS: Twelve spontaneous hypertension rats were divided randomly into two groups: group of atorvastatin(atorvastatin 50 mg?kg~(-1)?d~(-1)) and group of SHR(0.5% mucilage of arabic gum,10 mL?kg~(-1)?d~(-1)).Additionally,six male Wistar-Kyoto rats(0.5% mucilage of arabic gum,10 mL?kg~(-1)?d~(-1)) were selected as control group.Systolic blood pressure was assessed with the tail-cuff method.After six weeks,entire heart,and left ventricle were weighed.The left ventricular weight index was calculated and myocardial hydroxyproline and collagen protein concentration were measured.The serum high sensitivity CRP(hs-CRP) was measured by nephelometry.The localization of vascular cell adhesion molecule(VCAM) in myocardium was investigated by immunohistochemistry assays.The level of NF-?B mRNA expression was detected with in situ hybridization.Ultrastructure in cardiac muscle was also observed under transmission electron microscope.RESULTS: The expression of myocardial VCAM and NF-?B in SHR group was stronger than that in WHY group.Compared with SHR group,entire heart weight,left ventricular weight,left ventricular weight index,serum hs-CRP,myocardial hydroxyproline and collagen protein concentration was decreased,the expression of myocardial VCAM and NF-?B in SHR group was weaker than that in atorvastatin treatment group.The myocardial pathological change such as incomplete karyotheca in cardiac muscle cells,no clear of transverse striation and the mess in myofibril alignment,and hyperplasy in interstitial collagen fibre were observed in SHR group and these changes were improved in atorvastatin treatment group.CONCLUSION: The cardiac remodeling in SHR is improved by atorvastatin.The molecular mechanism may be related to its down-regulating the expression of VCAM protein and NF-?B and inhibiting myocardial chronic inflammation.

Background Neointima formation plays an important role in the pathogenesis of atherosclerosis and restenosis after angioplasty.We hypothesized if atorvastatin inhibits neointima formation mediating decreases in cathepsin S (Cat S) and nuclear factor-?B(NF-?B) expression.Objective The study was aimed to explore the effect of atorvastatin on the neointima formation,Cat S and NF-?B expression in rats after balloon-injured carotid artery.Methods Twenty-four male Sprague-Dawley rats were randomly one of three arms:control group(n=8),surgery group(n=8) and atorvastatin group[10 mg/(kg?d),n=8] for 4 weeks.Surgery and atorvastatin group were performed with balloon angioplasty to the left common carotid artery.The serum levels of IL-1? were measured using enzyme-link-immunosorbent assay(ELISA).Carotid arteries were excised and examined with pathomorphology.The expression of Cat S and NF-?B was measured using using the RT-PCR and immunohistochemistry techniques.Results Compared with surgery group,atorvastatin decreased intima area and intima media ratio(I/M)[intima area:(148.6?8.8)?103 vs (64.8?5.1)?103 ?m2;I/M:(2.1?0.2) vs (0.9?0.1),all P

Objective To observe the clinical efficacy and safety of local injection of botulinum toxin type A (BTX-A) in the treatment of Migraine.Methods 31 patients in the treatment group were injected BTX-A 25 U at 10 positions at the muscles.30 patients in the control group were given 2％ lidocaine 1 ml plus prednisolone acetate 1 ml at the same muscle sites as in the treatment group.Days,frequency,and intensity of headache were evaluated by visual analogue scale (VAS),migraine disability was evaluated by migraine disability assessment guestionnaire (MIDAS),and adverse reactions were assessed on 1 month before the treatment and 1st,2st,3st months after the treatment.Results The therapeutic effect between the treatment and control groups was significantly different in terms of days,frequency,and intensity of headache and migraine disability.Compared with preinjection,days and frequency of headache and migraine disability were decreased significantly after injection in treatment group,lasting more than 2 months.No patients in two groups reported any serious treatment-related adverse event.Conclusions Botulinum toxin type A in the treatment of Migraine is effective and relative safe,and can decrease migraine disability.

ObjectiveTo study the situation of neural invasion in pancreatic cancer and investigate its related clinical factors. Methods The neural invasion in 73 cases of pancreatic cancer patients was retrospective analysed. The correlation between neural invasion and clinicopathological parameters,and survival rate was investigated.Results In 73 cases of pancreatic cancer,neural invasion occurred in 38(52.1％) patients,among whom intra-pancreatic neural invasion rate was 15.8％ (n =6) ; and both intrapancreatic and external pancreatic plexus invasion rate was 84.2％ ( n =32).Neural invasion was not related with gender,age,and pathological type,degree of differentiation,tumor size and lymph node metastasis (P ＞ 0.05 ).But the presence of abdominal pain,vascular invasion,the expression of EGFR and VEGF in tumor tissue was significantly related with neural invasion (P ＜0.01 ).The median survival of patients in neural invasion group was 8 months,which were significantly shorter than that of in patients without neural invasion (13 months,x2 =4.69,P =0.030).Conclusions Neural invasion has a high incidence in pancreatic cancer,and it can cause obvious abdominal pain.And it is related with vascular invasion and the expression of EGFR and VEGF in tumor tissue.Neural invasion is one of the factors affecting the survival rate.
